My debouce is currently set to 3000.  I've ran it as high as 10000 with no luck.  Sometimes it takes 5 minutes before going into reset, and other times it will go for an hour.

General Mach Discussion / Source of noise

I have a cnc plasma table that I've built and have been using for over a year now.  Occasionally Mach goes into reset on it's own.  I'm trying to identify the source.  Other than putting a data logger on all of the input pins, is there any way to have Mach create an event log that will identify the pin(switch) that's tripping the reset?

Hood,

Thanks for the reply.  After looking through the Wiki I came up with the same solution.  I created a M101.m1s file in my macro subdirectory and used the DoOEMButton(123) command (OEM 123 being the THC toggle).  In Sheetcam I insert an M101 code before the hole cutting operation, which toggles the THC off, and another M101 code after the hole cutting operation, which toggles the THC back on.  Works great!!

Jcar,

General Mach Discussion / Mach3 - Campbell THC Help

« on: October 02, 2007, 02:51:54 PM »

Gentlemen,

I have my cnc plasma table up and running using Mach3 and Bob Campbell's THC300 torch height controller.  Everything works very well, except small holes (ie..3/8").  I can change my THC settings in Mach3 and get reasonable results, however these settings don't work so well for other more general cuts.  I can get very nice holes without using the THC (ie.. fixed cutting height).  Does anyone know of a macro or g-code that can be used to enable / disable the THC from within a program.

Thanks,

Jcar,
